Abstract
Methods for controlling the net-displacement of a rotary fluid pressure device are disclosed. One of the net-displacement control methods () includes obtaining a desired input parameter () and a relative position () of a first member () and a second member () of a fluid displacement mechanism. A determination of a first and second output value is then made for each of a plurality of volume chambers () when the volume chambers () are supplied with fluid at fluid inlet and fluid outlet conditions, respectively. A total output value is then computed for each of a plurality of control valve configurations () and compared to the desired input parameter (). The control valve configuration () with the total output value most similar to the desired input parameter () is then selected. A plurality of control valves () are then actuated in accordance with the selected control valve configuration ().
